Description

Technical Field

[0001] This utility model relates to the field of spray gun performance testing, and in particular to an offline testing device for the atomized water spraying effect of a continuous casting spray gun. Background Technology

[0002] As a key piece of equipment in the continuous casting process, the spray gun's atomized water spraying effect plays a decisive role in the quality of the continuously cast billet. During continuous casting, the spray gun can precisely and evenly spray atomized water or air-mist mixture onto the surface of the high-temperature steel billet. With its precise cooling rate control mechanism, it effectively inhibits crack propagation and refines the grain structure, thus becoming a key guarantee for eliminating subcutaneous bubbles and center segregation defects in the continuously cast billet. This greatly improves the overall quality of the continuously cast billet and occupies an irreplaceable and important position in the continuous casting process. After the spray gun is manufactured, it undergoes strict inspection to ensure its stable and efficient functioning, thereby guaranteeing its quality.

[0003] However, in the existing technology, spray gun inspection mainly focuses on judging obvious faults such as whether the nozzle is blocked or whether the spray gun body is damaged, while paying relatively little attention to key issues such as the atomization effect of water spraying, such as atomization cone and coverage uniformity. This leads to quality problems such as uneven cooling and local overcooling after the spray gun is put into operation, which seriously affects its performance. Utility Model Content

[0004] The purpose of this invention is to provide an offline detection device for the atomized water spraying effect of a continuous casting spray gun, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an offline detection device for the atomized water spraying effect of a continuous casting spray gun, comprising an operating table and a fixed plate. A first support plate is fixedly connected to the upper end of the operating table. A water inlet pipe is provided inside the first support plate. A first control valve is provided inside the water inlet pipe. A flow meter is provided inside the water inlet pipe near the first control valve. A second support plate is fixedly connected to the upper end of the operating table near the first support plate. An air inlet pipe is provided inside the second support plate. A second control valve is provided inside the air inlet pipe. A pressure gauge is provided inside the air inlet pipe near the second control valve.

[0006] The fixing plate has a through hole, and a clamp is installed inside the fixing hole. The spray gun body is installed inside the clamp. A first connecting pipe is fixedly connected to the upper end of the spray gun body. A positioning rod is fixedly connected to the upper end of the spray gun body near the first connecting pipe. A second connecting pipe is installed at the upper end of the spray gun body away from the first connecting pipe. A positioning hole is opened at the lower end of the fixing plate near the fixing hole.

[0007] Preferably, a baffle is provided at the upper edge of the operating table, an electric push rod is provided at the upper end of the operating table near the baffle, a connecting seat is fixedly connected to the upper end of the electric push rod, and a guide rod is fixedly connected to the upper end of the operating table near the electric push rod.

[0008] Preferably, the connecting seat has a guide hole inside, the upper end of the connecting seat is provided with an installation block, the installation block is provided with a fixing bolt inside, a short rod is fixedly connected to one side of the installation block, a moving plate is fixedly connected to the other end of the short rod, a cleaning pad is provided on one side of the moving plate, a water collection tank is provided inside the operating table, and a drain pipe is provided on the right side of the operating table.

[0009] Preferably, the number of positioning rods is two sets, and they are symmetrically arranged about the center line of the fixing plate.

[0010] Preferably, the connecting seat slides outside the guide rod via an electric push rod.

[0011] Preferably, the movable plate is movably connected to the connecting seat via a short rod, a mounting block, and a fixing bolt.

[0012] By adopting the above technical solution, the water inlet pipe and air inlet pipe are connected to external pipelines, and the first control valve and the second control valve are opened. Under the action of the valves, water and gas enter through the water inlet pipe and air inlet pipe respectively, and are sent into the spray gun body under the action of the first connecting pipe and the second connecting pipe. Under the condition of continuous external power supply, water is sprayed out from the inside of the spray gun body to form water mist. At the same time, the operator can observe the water mist pattern in real time through the transparent baffle. In addition, the operator can also use flow meters and pressure gauges to monitor water pressure and air pressure parameters so as to adjust the operating parameters according to the actual working conditions. The components such as the water inlet pipe, air inlet pipe, first connecting pipe, and second connecting pipe can simulate the actual operating conditions of the spray gun, and then judge based on the atomization cone and coverage uniformity of the water mist, effectively avoiding quality defects caused by uneven cooling or local overcooling, and ensuring that the spray gun reaches the optimal performance state before being put into formal use.

[0013] Using the above technical solution, by activating the electric push rod, the connecting seat and scraper move upward. During the scraper's movement, the cleaning pad rubs against the inner wall of the baffle. With the continuous output of the electric push rod, the scraper and cleaning pad move up and down in a cyclical manner, thereby wiping and cleaning the water stains on the inner wall of the baffle. In addition, the operator can disassemble the moving plate using the fixing bolts, facilitating regular maintenance of the cleaning pad. The water collection tank can collect the water sprayed from the spray gun body and reuse it, effectively improving the efficiency of water resource utilization. The moving plate can be cyclically moved by components such as the electric push rod, connecting seat, and guide rod, thereby cleaning the baffle and effectively avoiding blind spots caused by water stains, while also improving the clarity and reliability of real-time observation.

[0028] Working Principle: When using this offline testing device for the atomized water spraying effect of a continuous casting spray gun, firstly, align the positioning rod 16 of the spray gun body 13 with the positioning hole 14 in the fixing plate 2 for installation; simultaneously, ensure that the first connecting pipe 15 is inserted into one end of the air inlet pipe 8 and the second connecting pipe 17 is inserted into one end of the water inlet pipe 4. Then, pass the clamp 12 through the fixing hole 11 and rotate the bolts at its upper and lower ends to firmly fix the spray gun body 13.

During the scraper's movement, the cleaning pad 28 rubs against the inner wall of the baffle 18. With the continuous output of the electric push rod 21, the scraper and cleaning pad rub against each other. The pad 28 moves up and down in a circular motion to wipe and clean the water stains on the inner wall of the shield 18. In addition, the staff can disassemble the moving plate 27 through the fixing bolt 29 to facilitate regular maintenance of the cleaning pad 28. The water collection tank 19 can collect the water sprayed by the spray gun body 13 and reuse it, effectively improving the efficiency of water resource utilization. The moving plate 27 can be moved in a circular motion through components such as the electric push rod 21, connecting seat 23, and guide rod 22 to clean the shield 18, effectively avoiding blind spots caused by water stains, and also improving the clarity and reliability of real-time observation.
